(o1. zzz-) 1 Claim l This invention relates to a piercing pin valve construction particularly adapted for use in connection withV a syphon vase for the purpose of charging the vase with CO2 or thelike, fromA a Sparklet'bu'lb.

Oney object of the invention is tov provide a valve construction wherein a single valve element acts as. a check valve. aga-inst the outward ow of gas oncev the syphon vase has been charged, and eliminates the usual arrangement oi a valve seat and a valve plug or disc for seatingthereon;

Another object is to provide a valve construction for association' with a. piercing' pin, including a valve element which may be made of. synthetic rubber or the like, and which is readily renewable from the outside of the. vase in a; comparatively simple manner. n

Still another object i's to provide a valve construction in. the form of a fitting, soldered or otherwise secured in the wall ci. a syphonl vase, the itting having a. bore adapted to receive a valve element and a retainer for the valve element, the retainer also serving as a means to support a piercing pin.

A further object is to provide a fitting so constructed that it is adapted to receive a sealing sleeve for the neck of a bulb of gas and is also adapted to coact with a holder for the bulb to eil'ect sealing of the bulb and piercingof the neck thereof by reason of such coaction.

With these and other objects in view, my inventon consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, wherein:

Fig. 1 is a side elevation partly in section of a syphon vase with my piercing pin valve construction installed therein and shown in side elevation, a bulb and a bulb holder being associated with the piercing pin valve construction.

Fig. 2 is an enlarged sectional view through the valve construction per se, and an adjacent portion of the bottom wall of the syphon vase; and

Fig. 3 is a similar view showing the association of a bulb and a bulb holder with the piercing pin, and showing the operation of the valve element.

On the accompanying drawings I have used the reference numeral I0 to indicate a syphon vase such as one of the type shown in my copending application Serial No. 643,262, filed January 25, 1946. This type of vase has a detachable head I2 for lling. purposes the head jhaving a. discharge spout I4, and an operating handle I6 for opening the valve in the head to permit. dischargev of carbonated water or the like from the vase. Within the vase a syphon tube I8 extends "from a position adjacent the bottom thereof and up to the valve andthe nozzle in the usual manner. The vase I Ilv has a bottom 20, preferably formed as al stampingy with its Vperipheral edge located within a return bent flange 22 of the vase I0, and' soldered thereto as,I indicated at 24..V .l n v A..iit ting F isprovided havingv from bottom to top athreaded. portion 2.4 a cylindrical portion 26, and a shoulder portion 28'. The cylindrical portion 26 is tted in a sleeve 3,6 formed at the center of the bottom 2U' and soldered therein. as indicated at 32.V The fitting. F has a bore comprising anintermediate portion 344 of one size, a portion 36 below it somewhat smallerr anda third portion. 38 above the'portion 3.4. which is. threaded to receive a valve elementI retainer 40 for it.

Above the element 40 is a valve element V having a flanged portion 42 and a dom-e shaped portion 44. 'I'he bottom of the ilange 42 is formed to iit a projection 46 on the retainer element 40 and the valve element above this projection has a recess 48. The valve element V may be formed of synthetic rubber or the like, and is provided with a passageway 50 formed by thrusting a needle vertically through the valve element from the recess 48. The proportions of the parts `should be such that when the retainer element 40 is secured in the position shown in Fig. 2, the ilange 42 is under suiiicient compression to form a seal against the escape of gas under pressure.

'Ihe retainer element 40 is provided with a pair of openings 52 to receive a Spanner wrench for screwing it into position. Its lower end is provided with a tubular piercing pin 54 of hardened steel or the like. The piercing pin is retained in position by swedging a hub 56 on the lower end of the retainer element into an annular groove 56 of the piercing pin. The piercing pin is provided with a central passageway 60 which communicates with a central passageway 62 through the retainer element 40.

A sealing sleeve 64 is forced into the cylindrical portion 34 of the bore of the fitting F to a position above the shoulder 36 thereof, which shoulder retains it in position against subsequently being pulled out when removing a charging bulb from position. This makes for a simple assembly and likewise disassembly when it is desirable to renew the parts V and 64. The part 64 is rst removed and then the retainer 40 can be screwed out of position by means of a spanner wrench cooperating with the spanner holes 52, whereupon the valve element V may be removed and another one inserted. The retainer element 49 can then be screwed back into position and a new sleeve S4 pressed into position.

The valve element V operates in the following described manner: When a bulb Bis associated with the syphon vase by engaging the neck 66 of the bulb with the sleeve 64 as in Fig. 3, a seal is effected. The bulb is forced into the sleeve by a bulb holder 68 screwed onto the threaded portion 24 of the fitting F as in Figs. 1 and 2, the first operation being contact of the neck 66 with the lower end of the sleeve 64. Thus a seal is started and as the neck is forced up into the i sleeve, the sleeve expands from its tapered posif,

tion of Fig. 2 to its expandedv position of Fig. 3L This tapered arrangement facilitates insertionlofl the sleeve 64 into the fitting F during initial assembly and provides clearance around the sleeve so that it can expand as in Fig. V3 for pro-v viding an encient seal against the escape of gas from the tting around the neck of the bulb as the bulb is forced into position.

During movement to the position shown in Fig. 3, the sharpened lower end ofthe piercing pin 54 will pierce the upper end of the bulb neck thereby releasing the gas therefrom which flows upwardly through the passageways 69 and S2, and into the recess 48. 'I'he gas being under pressure goes on upwardly through the needleformed passageway 50,. opening it up as illustrated in Fig. 3 to permit ready flow in an upward direction.

Due to the dome shaped top 44 of the valve element, when the bulb B is removed the gas pressure on the liquid that is then contacting the top of the valve effects a depression of the valve as to the dotted position, thus tightly closing the passageway 50 against subsequent outward flow of gas and/or liquid. Thus the single 4 valve element V operates as an eflicient check valve and eliminates the troubles encountered with proper seating of a valve disc or plug on a valve seat as in usual check valve installations.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose.- of my invention, and'l it fismy rintention to cover by my claim and modied forms of structure or use of mechanical equivalents which may be reasonably included within its scope.

I claim as myinvention:

In a piercing pin valve construction, a valve body, avalve element of rubber or the like therein having a flanged base and a domeshaped projection therefrom, the central portion of said base havinga recess therein, said valve element having a pierced opening from said recess to the top of said projection, a retainer for said valve element screwed into said valve body and stoppedby shoulder .within the valve body to place said flanged base under predetermined compression, said valve body having a socket terminating in an inwardly directed shoulder conforming to and conning said base and hav-l ing a further shoulder conforming to and conning asubstantial portion of the said domeshaped projection.
